HANGER FOR SHAFTING.

Speccaton of Letters Patent No. 19,340, dated February 16, 1858.

To all whom 'it may concern.'

Be it known that I, l/VILLIAM B. BEMENT, of the city of Philadelphia andState of Pennsylvania, have invented a new and useful Improvement inHangers for Shafting of Mills, Factories, &c.; and I do hereby declarethat the following is a full, clear, and exact description of theconstruction and operation of the same, reference being had to theaccompanying drawings, making a part of this specication, in which-Figure l is a geometrical side elevation of the improved hanger; Fig. 2,a like front elevation of the same; Fig. 3, a vertical section of thesame; Fig. 4, a horizontal section (through F, F of Fig. l) showing therelative positions of the adjusting screws, stem, and bushing of the boxholder for the same; Fig. 5 is a side elevation of the pillow block withthe same improvement applied which is shown in the Figs. 1, 2, and 8;Fig. 6, a front elevation of the same; and Figs. 7 8, and 9 arerepresentations of the same improvement adapted to trunnions for thesame purpose; Fig. l0 denotes a side elevation of the hanger with theannular part B, of the box holder, and the box C, and shaft below thehanger, or showing the hanger elongated; Fig. Il is a transverse andvertical section of Fig. 10, showing the capabilities and relativearrangement of parts for universal adjustment of the line of shaft, box,and of box carriers position all combined in the same hanger; Fig. l2 isa plan of Figs. 10 and 11 with front end of hanger broken olf to showparts below, and how the shaft may be run in any direction or line inthe horizon or complete circle when below the hanger, and the same abovewith the except-ion of the slight thickness of the body of the hanger;also showing how the shaft may be run on any angle with the hanger andstill have all the universal coperative adjustments, at the same time asto line of shaft, and position of box whether above or below the supportas hereafter seen.

Like letters indicate the same parts, when on the different figures.

The nature of my invention consists of my within described main part ofthe hanger so constructed as within described as to so receive the partsconnected to and to coperate with it, that the shaft and box may haveboth an universal line adjustment, and a universal position adjustment,and l also to run above or below the support part of the hanger, in themanner hereinafter described. And in the relative arrangement andoperation of the several parts, in combination with each other, and thehanger, as to allow the shaft an universal line posi'- tion as tohorizon; to be operated above or below the hanger, (or that portionwhich supports it) for the desired elevation, and at the same time allowan universal radial self-adjustment of the box, to coperate with theshaft, and so that the box and shaft may both have an universal positionadjustment so as to be moved to find any point or location within thescope limits of the hanger, and so secured, to constitute it a completemachine for the purpose designed, all as will be hereafter seen.

B, the annular part of the box support or holder; C, the box throughwhich the shaft-ing passes; E, the bushing surrounding the stem of theholder; F, the set screws for adjusting t-he box holder horizontally; Gand H, screw nuts adapted to a thread which is cut upon the stem (K) ofthe box holder.

I, represents the tubular part of the hanger through which the stem ofthe box holder or supporter is inserted, and around `and through theupper part of which the adjusting screws (F) are radially inserted; andO, O, are pointed screws for supporting the box when applied by means oftrunnions. The dotted lines A, B, and C D are vertical and horizontalindications of the center of the shafting.

The stem of the hanger may be made in the usual form, and as usuallyadapted for being secured by bolts and nuts. The part to which the boxis usually applied I make of an elliptical form and tubular, and so thatit shall be in a vertical position when the hanger, pillow block orbracket is applied; and through this, the stem (K) of the box supporter,having a thread cut upon it, is adapted to slide freely up and down, andalso so as to be capable of being firmly adjusted therein at any height(within proper limits by means of the two screw nuts (G and H) which areadapted to the thread thereon and so as to bear respectively againsteach end of the tube, as shown in the drawings. The upper side of theannular part of the box holder (B) has a socket adapted for receivingand holding the box by means of a spherical form given thereto-(anarrangement well known and therefore not needing a description). Thisannular part (B), is also constructed so as to be a fixed part of thescrew stem (K), and consequently the box is carried up or down with thesingle stem as the latter is raised or lowered by operating the nuts Gand H.

The box (C) is constructed in the usual manner, being fitted with oilcups and conducting holes on the upper side and adapted for thereception of the shaft.

For the purpose of effecting the horizontal adjustment of the box holderin directions at right angles with the shafting, I make the upper partof the tube (I) larger' than the lower part, so as to allow of sufhcientroo-m being made within the same for the reception of the bushing whichsurrounds the stem (K) at this point, and also so as to allow ahorizontal movement of the said stem and bushing in directions at rightangles with the shafting, when the set screws (F, F, F,) are operatedfor the purpose of adjusting the same, as shown in Fig. 4. These screws(F) are placed radially around and through the sides of the tube (I) soas to bear with their inner ends against the bushing as shown in thesame figure. Now the tube (I) being also elliptical in its bore, or onthe inner side, and having its longer diameters at right angles with theshafting, and its shorter diameters about equal with the diameters ofthe stem (K) and the bushing respectively, it will be manifestthat thestem fitting closely through the bushing (E), is capable of beingreadily moved therewith in the horizontal direction mentioned, by simplyoperating the set screws (F, F, F) accordingly, and that the said stem(K) supporting the box or bearing` (C) of the shaft, and being capableof a vertical motion in the tube by means of the screw thread thereon incombination with the screw nuts (G and H) as before described the saidbox is therefore capable of being moved (within lproper limits) indirections either vertical, horizontal or in any resultant of the twocombined-which in connection with the independent ball and socket motionwhich the box has within the annular part (B) of the support, enablesthe workman at any time, readily to bring the center of the shaft tocoincide `perfectly with any point (within necessary limits), withoutrequiring any readjustment of the hanger, and without removing the saidshafting therefrom--as has heretofore been necessary whenever the saidhangers &c. have gotten out of line, a result of very frequentoccurrence, and arising from the sinking of parts of the building,shrinking of the beams to which the attachments are made, and othercauses.

It requires a close examination of the before described adjustabilityand parts constituting it to comprehend the full extent and effect ofthis improvement as follows, by the vertical adjustment of the generalposition of the box by means of the stem K a vertical adjustment only;would be had, while by the arrangement described a vertical, horizontal,transverse and in fact an universal adjustment is had, of the shaftsposition in every direction, whereby any and every point or positionwithin the scope limits of the hanger can be readily found andpermanently secured, and combined with the universal self adjustment ofbox and shaft to each other, this result is due to the novel andrelative arrangement of the different parts of the hanger in combinationwith each other, and the main part of the hanger, it is of vitalimportance and the hanger would not be a complete machine without it. l

The same improvement may also be applied to boxes upon trunnionsconstructed as usual, by means of set screws O, O, which are pointed soas to iit in conical depressions made in the ends of the trunnions asshown in Fig. 7, the support for the trunnion screws, being formed so asto receive the box and be adjustable in the vertical and horizontaldirections by means of the screwstem and nuts (G and H), and the setscrews (F) as before described and set forth. It will be perceived thatmy invention is applicable to all kinds of supports for shafts of mills,whether the said supports are suspended from above, secured against awall, or resting upon abase; and that the box for the shaft can besupported equally well for the purpose, whether the screw stem (K) beabove or below the box This arrangement allows of placing and runningthe shaft above the support of the hanger where the room is low and thepulleys small in diameter which constitutes the hanger a short one; andallows the shaft to be placed and run far below the support of thehanger which constitutes the hanger a long one, thereby allowing` verylarge lpulleys to be used thereon as seen at Figs. 10, 11, and 12, italso will allow the line of shafting to be placed, and run in any linewithin the whole horizon, below the hangers; and nearly so when theshaft is above the support as seen by red lines A2, Fig. l2, and stillby the construction and peculiar combination of parts, allow of theshafts and box universal self adjustment to each other, or to cooperatefreely together and at the same time allow of an universal adjustment asto general position of shaft. This is also a very important improvementand wholly due to the peculiar construction and arrangement of the partsconstituting my invention.

The advantages of my invention are that a line of shafting, or a singleshaft, can in case of the settling` of the building, shrinking of thebeams, or Wearing of the boxes or bearings, be easily and firmlyreadjusted or relined, at the same time, Without readjusting the hangers&c. and Without removing the. shafting therefrom as before stated.

Having thus described t-he construction and operation of my invention,and pointed out peculiar facts showing its great utility- I proceed tostate that I do not claim supporting a box or bearing for a shaft upontrunnions cast on the box; nor suspending the same upon the pointed endsof screwsnor do I claim the more common arrangement for holding the boxso as to allow a universal motion i of the same, by means of the balland socketf nor do I claim adjusting the same vertically, by means of ascrew and two nuts, the former sliding up and down in a cylindricaltube.

lVhat I claim as my invention and desire to secure by Letters Patent is,

l. The main part or body of the hange A, or its equivalent, when soconstructed as to receive the parts Which are so connected to, and tocoperate With it, that both the shaft and box shall have an universalline adjustment and an universal position adjustment, and at the sametime allow the shaftto be placed and run above or beloW the support partof the hanger, in any and every horizontal and angular line,substantially in the manner and for the purposes fully described and setforth.

2. I lclaim the construction of the single stem (K) carrying the box (C)and so arranging it relatively with and connecting it to the hanger orsupport by bushing that the box and shaft shall have a coperative selfand universal line adjustment With each other, and the shaft have anuniversal position adjustment so as to be moved readily to ind any andevery point or location within the required limits and be securedthe-rein, and so that the line of the shaft may be placed and run abovethe support or below the hanger to constitute it a long or short one,and also receive any and every line and self adjustment positions Withina complete horizon or circle, essentially in the manner and for thepurposes fully set forth and described.
